Fully heavy dibaryons

The existence of fully heavy dibaryons Omega(ccc)Omega(bbb), Omega(ccb)Omega(bbc), Omega(ccc)Omega(ccc), and Omega(bbb)Omega(bbb) with J = 0, 1, 2, 3 and P = +/- 1 are investigated in the framework of a constituent quark model with the help of the resonating group method. The dibaryon composed of six c or b quarks with J(P) = 0(+) is able to be bound, because the requirement for antisymmetrization between the same baryon clusters introduces an attractive interaction between two fully heavy baryons. Although it is difficult for the dibaryon with the color-singlet type Omega(ccc)Omega(bbb) to form any bound state, it is possible for the Omega(ccb)Omega(bbc) state to be bound. The channel coupling of all channels of both Omega(ccb)Omega(bbc) and Omega(ccc)Omega(bbb) structures leads to the bound conclusion of this fully heavy system composed of three c quarks and three b quarks.

Automated summary

This study investigates the existence of fully heavy dibaryons Omega(ccc)Omega(bbb), Omega(ccb)Omega(bbc), Omega(ccc)Omega(ccc), and Omega(bbb)Omega(bbb) with specific quantum numbers in a constituent quark model framework. The findings suggest that under certain conditions, fully heavy dibaryons composed of specific quark combinations may form bound states, providing theoretical basis for the formation of fully heavy systems.
